Here is the A4 size LibreLogo flyer made for the LibreOffice booth at FOSDEM 2014. It contains a maze and its compact LibreLogo source code. This SVG animation shows its work. The source code of the program:
HIDETURTLE PENUP FILLCOLOR “BLACK” REPEAT [ RIGHT 90 REPEAT REPCOUNT [ z = INT RANDOM 2 RECTANGLE [3.5+21*z, 3.5+13*(1-z)] FORWARD 10 ] ]
One of the results of the 2-day LibreOffice hackfest after the conference is a small improvement for LibreLogo: now code formatting/translation doesn’t modify the comments of the program (see this and other achievements of the hackfest).
